Quality Control

Our Etioporphyrin Iii is produced and controlled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment, spectroscopic identification (UV-Vis, IR, NMR), and residual solvent analysis to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) with detailed batch-specific data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This product is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain stability and purity.
